Expensive original iPhone Or Cheap Factory Unlocked Original iPhone 5/ 5S Refurbished Phone?

As we all know, the Apple iPhone is rather expensive, and the quality is very good. Now there are some iPhone refurbished phones with the prices much lower than the former. What is your choice?

Original iPhone 5 WCDMA 16GB Refurbished phone, $189.99;
Original iPhone 5S WCDMA 16GB Refurbished phone, $206.99;

If prices keep increasing, would you start buying refurbished flagship phones instead?

What current phone are you using? If prices get increased, would you buy a phone according to the trend or a refurbished phone instead?

Should I buy last year’s flagship phone or a new mid-range phone at the same price?

Battery life is not a priority for me. What’s better? Refurbished flagships or new mid-range phones. Any phone recommendations? Share with me the features mentioned below?

Nokia 8.1 not available anywhere

I am interested in buying Nokia 8.1 but it isn't available on Amazon or Flipkart. Is there any other site where it's available? I don't want open box/refurbished phone.
